Greenwald and Laura Poitras, the U.S. journalists who reported on spy agency analyst Edward Snowden's leaks exposing mass government surveillance, returned to the United States on Friday for the first time since revealing the programs in 2013. Greenwald and Poitras flew into New York's John F. Kennedy International Airport on the same flight to receive a George Polk journalism award for their reports on how the U.S. government has secretly gathered information on millions of Americans, among other revelations.

Journalist Glenn Greenwald Refuses To Confirm Or Deny He Has A New Leaker

The classified documents published by The Intercept were dated August 2013 — months after famed National Security Agency leaker Edward Snowden, who had previously leaked a cache of classified documents to Greenwald, had already fled the U.S.

The documents were not attributed to Snowden, as others were in numerous Greenwald stories over the last year revealing bulk signals intelligence agency surveillance programs.

According to Greenwald, more of those stories are still to come.

“There are definitely still more stories based on Snowden documents coming,” Greenwald wrote.
